Google Analytics Tracking Code History

Few months ago (2010 July), Google released a new tracking code for Google Analytics, featuring asynchronous JavaScript. If you haven't updated yet, you should do it now. It increases your page load speed noticeably. When during busy times such as morning or noon, the speeds up can be 1 second or more.

Now let's look at the JavaScript code ga.js. It is a minimized ＆ obfuscated JavaScript code. It has a total of 25k chars. It has 839 ;, and 383 {} pairs, and the function definition happens about 254 times. If you expand the code into lines, it's about over 1k lines, more likely close to 2k lines. When de-obfuscated but without rewriting functions, i'd guess it's 4k lines.
